High-speed Electric Arc Spraying Machine developed by our company offers high efficiency, low energy consumption and high-tech product. It is based on the electric arc as heat source, melting the metal wire, atomization and cooling with the compressed air, making the metal wire into small particles, and then sprays to the surface of the work piece after heat treatment with high speed, in order to obtain the ideal coating. The spray gun adopts stepless speed regulation. It can spray on the metal wires with different melting point, such as zinc, aluminum, zinc alloy, copper, lead-tin alloy, high carbon steel, and stainless steel.
